CALMET (California Meteorological Model), which is a meteorological subroutine for an air quality dispersion mode (CALPUFF; California Puff Model), closely related with the land surface structure. In this study, the sensitivity of micro-meteorological parameters including wind speed and roughness height, Albedo, Bowen ratio, soil heat flux, and leaf area index were closely evaluated with change of land-use in relation to urban development. As a result, although no consistent dependence of roughness height on surface wind was found, it showed that high value of surface roughness could lead to the increase of friction velocity, influence the Monin-Obukhov length and the mixing height. At the same time, the increasing Albedo reduced friction velocity and mixing height. Thus, it was concluded for the CALMET modelling that it is necessary to first define the roughness height, Albedo, and Bowen ratio according to land-use.
